Hanford Nuclear Reservation

An apparent surge in leakage from a huge tank of radioactive waste set off alarms at the Hanford nuclear site in south-central Washington. This involves an aging, double-shelled tank that contractors were slowly pumping out.

Higher-level managers for major Hanford contractors testified in a three-day U.S. Department of Labor hearing this week. The case is over the layoff of a whistleblower at the southwest Washington nuclear site’s under-construction waste treatment plan.

Hanford construction workers and managers testified in day two of a U.S. Department of Labor hearing Wednesday in Kennewick, where a different image emerged of  the site's under-construction waste treatment plant than is usually presented to the public.

Several former Hanford construction workers testified in a U.S. Department of Labor hearing in Kennewick Tuesday, saying managers at the nuclear site played dangerous pranks that ended in workers with bloodied fingers, an injured knee, a hurt arm and glue smeared across the face. 

Washington Gov. Jay Inslee wants a federal court order to bring more cooperation from the U.S. Department of Energy for cleanup of the Hanford nuclear site.

A federal court ordered the U.S. Department of Energy Friday to step up its solutions and timeline to clean up tank waste at Hanford in southeast Washington.

For a decade, one woman has been the top watchdog on the Hanford nuclear reservation for Washington state. Jane Hedges retires February 26.

In 1944, the U.S. pinned its hope on a secret project to win World War II. The government was counting on the B Reactor at Hanford in southeast Washington state to make enough plutonium in time. One of the physicists working against the clock was a 24-year-old woman: Leona (Woods) Marshall Libby.

About 10,000 people visit southeast Washington state’s Hanford Nuclear Reservation every year. And after a few hours on the bus, some are dazed like tourists who’ve seen one Italian cathedral too many.

On those tours, they have guides. But even folks who don’t come to Hanford’s physical site have a "tour guide" -- someone who can translate the language of Hanford and its nuclear legacy: Liz Mattson.

Federal officials are conducting an investigation after plutonium escaped off the Hanford nuclear site in Washington state. The plutonium is left over from a Cold War era factory at Hanford where plutonium was processed from a liquid into a solid form for bombs.

Wherever she was, she stood out for being half white, or half Japanese. Shirley Olinger will only whisper the racist names she was called as a girl.

In 1987, late in the Cold War, in a government reading room in Richland, Washington, a historian was studying newly released documents about the Hanford nuclear reservation. Then, a strange man approached her.

Hanford officials and community boosters In southeast Washington are hosting a celebration Thursday at an historic nuclear reactor. A signing ceremony in Washington, D.C., on Tuesday made the Manhattan Project National Historical Park official.

Cleaning up the central part of the Hanford nuclear reservation will take even longer. That’s the bottom line of a series of regional public comment meetings kicking off Wednesday in Richland, Washington.

Geochemist Frannie Smith would like to see more girls get into science like she did. Women make up only about 25 percent of geoscientists in the U.S. and only a quarter of all the scientists or engineers at the Pacific Northwest National Lab in Washington state are female.
